World’s first 100 mW deep-UV LED
LG Innotek says it has developed the world’s first 100-mW UV-C LED. The UV-C LED emits ultraviolet light with short wavelengths ranging between 200 – 280 nm and is also called deep UV. It is used in sterilizing and hardening devices with its ability to destroy bacterial DNA and cause chemical reactions with special materials. […]
Natural-spectrum LEDs get RG-1 Eye Safety certification
Seoul Semiconductor announced that SunLike Series LEDs, which implement light that closely matches the spectrum of natural sunlight, received an RG-1 Eye Safety certification based on the safety of its light source and was recognized for the highest level of safety among 25W COB type LED. Eye Safety certification is a rating based on safety […]
The difference between vehicular and non-vehicular LED drivers
There are numerous features in the electronics that power vehicular LEDs that you won’t find in other LED applications. Jatin Thaker, Dave Strycharz | NXP Automotive The automotive market is quickly moving away from traditional incandescent lighting towards more intelligent systems that promote reduced energy use, safety, and individualization options that boost brand recognition. Automotive […]
